Hello from the UK! :)

[Auto_Funk]

Hey guys!

How are you all doing? I'm Llewelyn, from Nottingham UK and I've just bought a 43000 mile '91 car which has been sat for 18 years untouched on a farm. I'm just starting my restoration journey and have been making some YouTube videos on it :)

Feel free to find me on there, I won't post a link in case it falls outside of the forum rules but I think I'm the only UK ZR-1 owner on there pretty much!
It is already on the register here from when Will the PO owned it.

The car was originally supplied to Germany and is a Euro car which is quite interesting. It came to England in 2000 and has been owned by the same guy since 2001. I purchased it earlier this year and will be doing a resto-refresh type job on it. What I mean by that is that I won't be completely disassembling it - Instead I'll be slowly restoring it whilst keeping it on the road and driving (unless something huge comes up of course!)

Here's a link to a recent Hagerty article on it which has some pictures:

Hey Llewelyn,welcome. Im the one that's been talking to you on Instagram. Any and all questions you could ever ask can be answered on this site. This is the black 91 that's been sitting for years that someone posted a story about it on the ZR-1 Registry page on Facebook.

Subscribed to your channel. Just watched part 4. You are getting on splendidly. Hope to hear it run in part 5.

I started watching with the first "barn find" video and then moved over to your channel. Definitely subscribed and am enjoying the series so far. You guys are doing a great job! It's neat to see the C4 (and especially the ZR-1) appreciated around the world! And of course there is a significance of the ZR-1 in England... prototypes met their grave there, but some were rescued and revived!

I, too, subscribed several days ago to your YouTube documentation of a black 1991 ZR-1.

I am especially interested in your project being I lived in Huntstanton and Heacham Beach (The Wash) Norfolk, England from 1959 to 1962 when my USAF father was stationed at RAF Sculthorpe. That is Lotus Motorcars country; Hethel, Norfolk, England.

I'm looking forward to your success with much anticipation.... :cheers:

Subscribed to your channel since last week! Here you have all the information you need to wake up your 91 ZR-1. Congratulations and good job!!

Hi all! Just catching up, I didn?t see these posts!

Thanks for your support with my project? it?s starting to take shape now, rear brake lines have been replaced (fronts okay for now) and I?m waiting on discs and calipers. Once they are done I should be able to drive to the pub! 😁

Annoyingly (off camera) I?m still chasing a misfire?


New fuel pumps, fuel filter, injectors
New coils, leads, plugs
New crank sensor
All vac lines tested and are working
All grounds cleaned including the block grounds
5 gallons of 98 Ron fuel in a clean tank
Code 31 and consistent misfire whether the engine is hot or cold

Frustrating!

I?m starting to run out of ideas now! But I?m thinking it could actually be the cam sensor which may have died when I got the car up to temp after 18 years of being laid up

I?ve got new o2 sensors, map sensor and a new IAC valve on the way. Hopefully I can source a cam sensor (I?ve contacted Phil). If it still doesn?t run properly after all that I might need to borrow an ECM from a UK owner to test? Any ideas? :)

Love the series thus far!

I'm sure this crew would be incredibly thankful for anything European export specific you can document. The metal identification plate near the right hood latch was one I had not seen before if you would be able to get a close up of that. :cheers:

Have you been able to setup any data logging aside from reading the codes manually? A relatively inexpensive ALDL -> USB cable, a copy of TunerPro RT www.tunerpro.net, and the 1991 ADX file from the link below should be able to do it. Heck, I'll buy you the TunerPro RT license if you want to try it.

I used this cable for my '94, but your '91 may need the 12-pin version if it isn't the same port.

I haven?t managed to do any proper diags yet - We have a Tech 2 for the C5 but I?m totally unfamiliar with OBD1 and what I?d need to access the data? I?ll read up on the links you sent!

I?ll post the vin plate next time I?m on a computer!

If there is anything else anyone wants to see just let me know :)

I?ve emailed Phil re cam sensor with no reply yet - I?m pretty desperate to get hold of the part, can someone drop him a message for me? It would be much appreciated!

Photo of the vin plate as requested ! If anyone wants to see anything else in detail please ask !

Also - Here's a video I posted privately for Jonny Smith showing the service history and paperwork for the car, might be of interest as it shows some of the German stuff:

Interesting photo of the vin plate! I never saw one of those. You still have the VIN number stamped in the front frame under the pop up driver light too?? In this place is my VIN number...

It is interesting to see a German vin plate on a C4! :)

I'm not sure about the frame stamp, I'll check next time I am working on the car!

In this place is my VIN number...Hey folks, allow me to add some German knowledge. what you see there is a standard German VIN plate. These are required on any car in addition to a VIN being stamped into the frame. So the VIN stamping as we know it is (most likely) still there AND there is the aluminum tag.

The plate gives some additional information such as manufacturer and model name, maximum load capacity, etc.

If the car comes without you have to add one, so did I on my Mark III and of course my ZR-1.

It is not actually checked by anyone. It's a useless piece of German bureaucracy. Only during our mandatory bi-annual federal inspection they make sure it's there.

I'm not too sure whether or not newer cars still have it. But it's definitely needed on older cars.

[1977CamaroZ28]

Thank's for the explanation Matt. Here in Spain it's not necessary to install another vin plate. They respect original one.

Auto_Funk, did you get your hands on a cam position sensor yet?

Excited to see this Z get back on the road nice job documenting and thanks for sharing. Certainly a worthy challenge. I have recently acquired the exact same 91 grey on black #1564, and have most things sorted now after a 20 year hibernation, covered and stored a lift indoors warm and dry so a sort of barn find and a somewhat easier undertaking. To date with only a few road trips to town , I can say it will be worth the effort as these are truly fabulous cars to drive. All the hype is completely true. A few more gremlins to sort and we can do a real road trip. Wishing you guys success and a heap of fun.

[Auto_Funk2]

Hi all! I hope you're all well! For some reason I can no longer post on my previous user account so I've opened a new one :) (mods would you be able to look at this?)

Russ I would LOVE a lift and a warm place to work on ours!! Thanks for the kind words and I hope you get yours to 100% also!

Still looking to try and source an ECM for ours which seems to be very tricky, I would rather buy one then send ours off for repair to eliminate downtime but also so we've got a spare... Any leads appreciated!

The current tires on the car are the Goodyear Gatorback OEM models correct? What was the plan for the replacements? The 315 rear tire sizes seem fairly rare with few options. Is that the same in the UK? Were you planning to go low cost? Or best available? Is the Michelin Pilot Sport All Season 4 (an OEM option on the C8) available in the UK?
